Interpretation of results of geological-geochemical studies of southern areas of West-Siberian oil and gas province (Demyanskaya and Nizhne-Keumskaya areas)
The paper presents the results of interpretation of pyrolytic studies using Bulk Rock and Reservoir methods in the Jurassic deposits of the Demyanskaya and Nizhne-Keumskaya areas (West Siberian Oil and Gas Province). The detailed study was necessitated by the significant prospect of their oil and gas potential. The content of organic carbon, the stages of thermal maturity, the type of kerogen and the generation potential for source rocks were determined. The composition of asphalt-resinous substances in coarse-grained sandstones was detailed
Mechanism of formation of increased natural radioactivity of deposits of the Osinskiy horizon in the south of the Siberian Platform
The paper gives a brief lithological characteristic and description of the patterns of the structure of the productive Osinskiy horizon of the Nepsko-Botuoba anteclise. According to the results of studies of rock radioactivity (gamma-ray, spectrometry), zones of increased natural radioactivity of the carbonate deposits of the Osinskiy horizon were identified and possible causes of its occurrence were formulated. According to the results of comprehensive laboratory studies, factors of endogenous and exogenous influence on the formation of zones of abnormal radioactivity values were identified
Lithological, petrophysical and geochemical support for well logging data interpretation to determine mass and volume concentrations of organic matter
The methodological basis of lithological-petrophysical and geochemical support of well logging data interpretation is substantiated to estimate mass and volume concentrations of organic matter on the basis of laboratory data. A method for separate assessment of the concentrations of kerogen and bitumen according to pyrolytic and bituminological studies has been developed. Methods for determining kerogen density that do not require dissolution of the rock mineral matrix are proposed. The list of necessary methods for determining kerogen density, according to the proposed methods, includes X-ray phase analysis, pycnometry, determination of porosity by the method of hydrostatic weighing and the method of nuclear magnetic resonance.
The results of the work are necessary for accurate determination of OM concentrations on the basis of well logging data.
Improving efficiency of development based on digital lithological and petrophysical models of productive layers
Тhe successful development of oil fields primarily depends on the most accurate geological understanding of the reservoir structure, determined by the correct lithological-facies and lithological-petrophysical and tectonic models. The complex geological model must accurately describe all the geological features of the reservoir for making further decisions on the methods and approaches to field development
The article outlines the problems of developing oil and gas fields in the Arctic Ocean, requiring the creation of submarine-ice floating vessels for the development of hydrocarbon resources in the freezing seas, and proposes an original design for drilling and production of oil and gas underwater floating structures (hereinafter — OGUFS). The article also describes the advantages of underwater placement of offshore oil and gas facilities at depths of approximately 138 meters below ice formations in comparison with the traditional Pentagon-88 type propulsion system. Based on these calculations, it was concluded that there is a significantly lower level of heat loss and that there is no icing problem in submarine floating structures, and the associated expediency of using this design in the development of Arctic shelf deposits is noted. A review of the remaining operational advantages of the subsea oil and gas facilities is provided
Calculation methods of determining physical and thermodynamical properties of natural gas. Methods of evaluating critical and pseudo-critical parameters of natural gas
The problem of adequate determination of the critical and pseudocritical parameters of natural gas is solved in the presence of initial data on the incomplete component composition A review of existing methods for determining the critical and pseudocritical parameters of natural gas in the presence of baseline data on the full component composition and on incomplete component composition (based on density data under standard conditions and the content of nitrogen and carbon dioxide) has been made. The results of the study of the limits of the possible application of the law of the corresponding states for natural gas are shown. New calculated dependencies of pseudocritical parameters are proposed with the aim of their application in calculation methods for determining the physical and thermodynamic properties of natural gas in computer models, mode calculations and technological problems of pipeline gas transport
This article presents the results of the analysis of the natural gas market made by a group of authors in the framework of a joint research work conducted by Gubkin Russian State University of Oil and Gas and the Royal Institute of Technology (Stockholm, Sweden). The trends in the development of world energy market are analyzed. The analysis of energy consumption and energy supply in the Asia-Pacific region as the most promising area for Russian natural gas exports is carried out. It is shown that the largest economies of the region such as (China, India, Japan and South Korea) need increasing larger volumes of natural gas to meet their growing energy needs, and it is Russia that can solve this problem by exporting natural gas through pipeline systems, as well as exporting liquefied natural gas
Approaches to planning nondestructive testing and technical diagnostics when repairing technological pipelines of oil and gas facilities
The article deals with the problems of technical diagnostics and non-destructive testing that arise during repairs of technological pipelines of oil and gas facilities. There are four main tasks of diagnostic repairs of technological pipelines, which differ both in the nature of the requirements for the results of diagnostics, the cost of monitoring, the accuracy of the results, and the equipment and methods used for monitoring. It is stated that there is currently no universal method for monitoring technological pipelines, which is applicable in all cases of assessing the technical condition of these structures during repairs
Increasing efficiency of workflow of thermo-mechanical impacts on soil during construction and operation of pipelines
The article presents the results of research on the technological efficiency of working processes of thermomechanical impact (TMI) on the soil. Taking into account the physical and technological features of the development of frozen and rocky soils, the analysis of the causes of unproductive energy losses that affect the efficiency of working processes is performed. Based on limitations and initial parameters of the TMI and the treated medium, the efficiency can be determined accurately enough and technically justified, and therefore ensure a stable efficiency with automated workflow management of low-temperature thermomechanical extraction of soils during the construction and exploitation oil and gas pipelines
One of the options for mounting parts on shafts is through the use of the friction method of transmitting torque with two contacting conical surfaces pulled together. However, traditional designs are not without drawbacks. The authors proposed a simple and compact design for reliable fastening of parts on the shaft in combination with the ability to quickly adjust their axial and angular position. New technical solutions are based on the improvement and diversification of the designs of tapered shrink sleeves
Many wells cease cost-effective production long before their deposits are depleted. Often this happens due to the accumulation of liquid at the bottomhole of a gas or gas condensate well. The accumulation of liquid occurs when the velocity of the produced gas becomes lower than that necessary to lift the fluid — this velocity is called the critical velocity. The injection of a foaming agent (or foam) to the bottomhole of a gas or gas condensate well is one of the promising methods of influencing a flooded gas or gas condensate well to control the amount of excess fluid in the bottom of a well. This method is not applicable in all cases: for example, the foam collapses in contact with condensate or simply does not form, and at high temperatures the formation of foam occurs less intensively. Gas well deliquification with foamers is a preventive method that allows for some time to reduce the amount of liquid in the borehole, correspondingly increasing the production of gas and gas condensate. In this work, we analyze the existing surfactants that are different in nature and type and present a new patented foaming agent that solves a number of problems: the presence of gas condensate in the well, high temperatures at the bottomhole, and high salinity of formation waters. Various laboratory tests of this foaming agent have been carried out, as a result of which the optimal concentration of the foaming agent and the possible limits of use in gas and gas condensate wells have been determined. For fields in difficult climatic conditions, a solid foaming agent has been developed and patented, which has similar properties to a liquid foaming agent
Investigating textural, structural and sorption properties of carbon-containing materiаls based on sludge waste from production of vegetable oils
The results of investigating the particle size distribution, structural, textural characteristics and sorption properties of a new composite carbon-containing sorption material obtained by thermal modification of kieselguhr sludge waste from the production of refined vegetable oils are presented. The processing conditions provide incomplete oxidation of organic impurities contained in the sludge waste, the formation of a mesoporous structure and the formation of soot-like carbon particles on the surface of diatomite particles. Using the Boehm method of IR spectroscopy and acid-base titration it has been established that the presence of various oxygen-containing functional groups on the surface of the carbon layer provide the materials obtained with bifunctional sorption properties as the effective extraction of heavy metal ions (using copper ions as an example) and oil products from aqueous media
